About OMRON Host Link Communications

The OMRONâ Host Link communications enabler supports OMRON
C-Series and CV-Series programmable controllers in point-to-point
and multi-drop configurations with one master device where the
CIMPLICITY Host Link Communications enabler acts as the master.

The OMRON Host Link Communications provides read
and write access to the OMRON programmable controllers via a Host
Link System Network. You can make RS-232 or RS-422 connections
through the built in Host Link interface on the programmable
controller's CPU or through an optional Host Link Unit in the OMRON
PC's rack.

All communication commands are implemented as
master/slave communications where the CIMPLICITY OMRON Host Link
communications enabler acts as the master responsible for
requesting data from or writing data to OMRON programmable
controller(s). Unsolicited data sent from OMRON programmable
controllers is not supported.

You can connect up to 32 OMRON programmable
controllers to a host computer via multi-drop RS-422 line.

You can connect to one OMRON C-Series or CV-Series
programmable controller via an RS-232 line.
